What should be paid attention to when laying underground direct buried cables?

What should be paid attention to when laying directly buried cables? Under what circumstances? For direct buried laying, it is necessary to consider whether the cable is easy to be damaged by external force impact.

1. If it will not be greatly impacted, it is possible to lay it directly.

2. If there may be some relatively large impact, but the strength can be controlled within a certain range, the armor can be directly buried.

3. If the external force is greater, it is necessary to use protective casing, which can be set locally (such as where the road passes).

Advantages and disadvantages of direct buried underground cable laying:

Advantages: convenient laying, saving materials and labor,

Disadvantages: inconvenient maintenance. If maintenance is required, the overburden needs to be excavated. It is only recommended to use it where maintenance is not considered or can be accepted. Yellow sand is usually required for direct burial.
